[wireless remote controller]

Abstract

A wireless remote controller includes a transmitter unit, which has a data storage device with an Express Card interface connectable to a main system directly for enabling the main system to store data into or fetch data from a flash memory of the data storage device, and a control device with operating buttons and a transmitting antenna, and a receiver unit, which is receivable in an open chamber of the housing of the transmitter unit when not in use and has a USB interface for connection to the main system for receiving control signals from the transmitter unit and transmitting received control signals to the connected main system.

1 . A wireless remote controller used with a main system, comprising a transmitter unit and a receiver unit, wherein: 
 said transmitter unit comprises a housing, said housing comprising an open chamber adapted to accommodate said receiver unit, a data storage device mounted inside said housing for storing data, and a control device mounted inside said housing and operable by the user to produce a control signal, said data storage device comprising an Express Card interface electrically connectable to said main system, a flash memory, and a flash memory control chip electrically connected between said Express Card interface and said flash memory, said control device comprising a micro-controller, a plurality of operating buttons mounted in an outside wall of said housing and respectively electrically connected to said micro-controller of said control device for operation by the user to produce a respective control signal to said micro-controller of said control device, and a transmitting antenna electrically connected to said micro-controller of said control device for transmitting control signals from said operating buttons to said receiver unit subject to the control of said micro-controller of said control device;    said receiver unit comprises a USB (Universal Serial Bus) interface connectable to said main system, a receiving antenna adapted to receive control signals from said transmitter unit, and a micro-controller adapted to transmit control signals received from said receiving antenna to said main system through said USB interface.    
     
     
         2 . The wireless remote controller as claimed in  claim 1 , wherein said control device further comprises a battery electrically connected to said micro-controller thereof.  
     
     
         3 . The wireless remote controller as claimed in  claim 1 , wherein said control device further comprises an indicator light electrically connected to said micro-controller thereof and adapted to give off light upon operation of said control device.  
     
     
         4 . The wireless remote controller as claimed in  claim 3 , wherein said indicator light is a light emitting diode.  
     
     
         5 . The wireless remote controller as claimed in  claim 3 , wherein said indicator light is a laser diode.  
     
     
         6 . The wireless remote controller as claimed in  claim 1 , wherein said control device further comprises sensor means electrically connected to said micro-controller thereof and adapted to detect an environmental status and to produce a control signal to said micro-controller of said control device upon change of the environmental status.  
     
     
         7 . The wireless remote controller as claimed in  claim 1 , wherein said control device further comprises a RF (Radio Frequency) circuit electrically connected between said micro-controller of said control device and said transmitting antenna for modulating signals subject to a predetermined frequency.  
     
     
         8 . The wireless remote controller as claimed in  claim 1 , wherein said receiver unit further comprises a RF (Radio Frequency) circuit electrically connected between said micro-controller of said receiver unit and said receiving antenna and adapted to demodulate control signals received by said receiving antenna.  
     
     
         9 . The wireless remote controller as claimed in  claim 1 , wherein said receiver unit further comprises an indicator light electrically connected to said micro-controller of said receiver unit adapted to give off light upon operation of said receiver unit.  
     
     
         10 . The wireless remote controller as claimed in  claim 1 , wherein said main system is a desktop personal computer.  
     
     
         11 . The wireless remote controller as claimed in  claim 1 , wherein said main system is a notebook computer.  
     
     
         12 . The wireless remote controller as claimed in  claim 1 , wherein said main system is a digital TV.
